The JPL Open Repository (JOR) replaced the JPL Technical Report Server (TRS) in 2023. It is a repository for digital copies of technical publications authored by JPL employees. It includes journal articles (the Final Accepted Version), meeting papers, presentations, and other publications cleared for external distribution from 1992 to the present. It also includes research datasets from 2022 on.

Years covered: 1992 to the present.
  • 1992-2021 records were originally on the JPL Technical Report Server (TRS) on Dspace system; those records were migrated to Dataverse in 2022.
  • Records with publication date 2022 or later are native to the Dataverse.
  • Data sets: 2022 to present
  • There are a few pre-1992 records. Those were added to the system on a case-by-case request basis.

  • Persistent IDs (PIDs):
  • 1992-2021 records have Handles
  • 2022 and later records have Digital Object Identifiers (DOIs).
    • Featured Dataverses

    In order to use this feature you must have at least one published dataverse.

    Publish Dataverse

    Are you sure you want to publish your dataverse? Once you do so it must remain published.

    Publish Dataverse

    This dataverse cannot be published because the dataverse it is in has not been published.

    Long-Term Variations in Total Solar Irradiance
    Jun 20, 1993
    Pap, Judit M.; Willson, Richard C.; Frohlich, Claus; Donnelly, Richard F.; Puga, Larry, 1993, "Long-Term Variations in Total Solar Irradiance", https://hdl.handle.net/2014/36482, Boulder, CO, JPL Open Repository
    For more than a decade total solar irradiance has been monitored simultaneously from space by different satellites. The detection of total solar irradiance variations by satellite -based experiments during the past decade and a half has stimulated modeling efforts to help identif...
    SOLERS22 Working Group 1 Report
    Jun 20, 1993
    Pap, Judit M.; Wehrli, Christoph, 1993, "SOLERS22 Working Group 1 Report", https://hdl.handle.net/2014/36577, Boulder, CO, JPL Open Repository
    SOLERS22 Working Group 1 had extensive discussions of current and future space and ground-based observations of total solar irradiance as well as near-UV, visible, and infrared irradiances during the 1-day SOLERS22 meeting held at the IAU Colloquium No. 143 on June 25, 1993. The...
    Analysis of a PWM-Resonant DC-TO-DC Converter
    Jun 20, 1993
    Vorperian, Vatche; McLyman, Colonel, 1993, "Analysis of a PWM-Resonant DC-TO-DC Converter", https://hdl.handle.net/2014/34991, Seatle, Washington, USA, JPL Open Repository
    When a parallel resonant tank is excited by a bipolar current pulse train a sinusoidal voltage develops across the tank whose amplitude depends on the duty cycle of the pulse train.
    Preface (for CUP)
    Jun 20, 1993
    Pap, Judit, 1993, "Preface (for CUP)", https://hdl.handle.net/2014/33678, Boulder, Colorado, USA, JPL Open Repository
    Study of changes in solar and stellar irradiances has been of high interest for a long time. Determining the absolute value of the luminosity of stars with different ages is a crucial question for the theory of stellar evolution and energy production in stellar interiors.
    Direct Broadcast Satellite-Radio, Space-Segment/Receiver Tradeoffs

    This paper looks at the balance between receiver complexity and the required satellite EIRP for Direct Broadcast Satellite-Radio (DBS-R).
    L-Band Mobile Terminal Antennas for Helicopters
    Jun 16, 1993
    Wu, T.K.; Farazian, K.; Golshan, N.; Divsalar, D.; Hinedi, S., 1993, "L-Band Mobile Terminal Antennas for Helicopters", https://hdl.handle.net/2014/35067, Pasadena, CA, JPL Open Repository
    The feasibility of using a low gain antenna (LGA) as a mobile terminal antenna for helicopters is described in this paper. The objectives are 1) to select the lowest cost antenna system which can be easily mounted on a helicopter and capable of communicating with a satellite, and...
    ACTS Mobile SATCOM Experiments

    Divsalar, Dariush; Simon, Marvin K., 1993, "Pseudo-Coherent Demodulation for Mobile Satellite Systems", https://hdl.handle.net/2014/35304, Pasadena, California, USA, JPL Open Repository
    This paper proposes three so-called pseudo-coherent demodulation schemes for use in land mobile satellite channels. The schemes are derived based on maximum-likelihood (ML) estimation and detection of an N-symbol observation of the received signal.
